  2. Pennsylvania Nonpoint Source BMP Effectiveness, Cost-Effectiveness, and Potential for Reducing Loads • Objective of extensive model analysis was to determine relative nonpoint source BMP effectiveness, cost-effectiveness, and potential load reductions that could be achieved – for TN, TP, and sediment. • Study considered 30 nonpoint source BMPs on 9 specific source categories - for the agricultural, urban, and septic sectors. • Results for effectiveness, cost-effectiveness, and loading reduction potentials should be viewed RELATIVELY among BMPs – rather than focusing on the absolute numbers. • The total annual costs are those reported in EPA UAA documents and documentation of “Estimated Stormwater BMP Costs” (in 2001 dollars) and reflect amortized capital costs plus annual O&M payments.

  3. Pennsylvania Nonpoint Source BMP Effectiveness, Cost-Effectiveness, and Potential for Reducing Loads • Potential load reduction numbers are reported since BMPs can be very effective and/or cost-effective, but there may not be potential for extensive implementation (or additional implementation beyond what is already on the ground). This measure is the maximum “window of opportunity”. • The loading reduction potentials are estimates of reductions beyond existing (2002) controls. • All nonpoint source BMPs are ranked according to their cost-effectiveness and potential for reducing nutrient and sediment loads beyond existing (2002) controls - with EQUAL WEIGHT given to cost-effectiveness and potentials. • Users of the information cannot simply add the potential load reductions for a group of BMPs to estimate the total reductions for a combination of practices.
